A baler is a machine used in agriculture and waste management to compress materials like hay, straw, or recyclables into compact bales. These bales are easier to handle, transport, and store. Balers can produce different types of bales, such as round or square, depending on the design and intended use. Balers are essential for farmers and businesses that deal with large volumes of materials. They help reduce waste and improve efficiency by making it simpler to manage bulk items. Common types of balers include hay balers, cardboard balers, and plastic balers, each designed for specific materials.
